// 函数名：LoadStreamOnHugeMemory
// 功能： 同上
// 第一个参数pvMem指向一块要打包的内存，第二个参数指明这块内存的大小
HRESULT LoadStreamOnHugeMemory(void pvMem, ULONG cbSize)
{
// Get Memory Handle:
HGLOBAL h = GlobalAlloc(GMEM_MOVEABLE, cbSize);
If(NULL == h) return E_OUTOFMEMORY;
LPVOID pv = GlobalLock(h);

// Copy to memory block

// Create stream on Memory:
HRESULT hr = CreateStreamOHGlobal(h, TRUE, &spStream);

return hr;
}
// stream now owns the memory
// unlock the data

// Create a stream holder. Load the stream holder from the global stream.
// THIS STREAM HOLDER IS INTERITED FROM IPersistStream
// And all virtual functions are Modified to handle the object....

//
// now, you have a big chunk of memory loaded into a ComVariant
//
// 现在你可以把打包后的CComVariant传递给MSMQMessege的Body属性了：
pisMsg->Body = vComData;
